SP-230-SS All-Season Heated Pyranometer

The SP-230 (All-season) is a heated pyranometer with a 0.2 W heater to keep water (liquid and frozen) off the sensor and minimize errors caused by dew, frost, rain, or snow blocking the optical path. Sensor includes IP68 marine-grade stainless-steel cable connector 30 cm from the head to simplify sensor removal and replacement for maintenance and recalibration.
